Great shots! I took the first one onto Photoshop. Added a little contrast and a touch of sharpening. Prize winner.I have a S100 with one trip on it with an Ike housing.. Here are some of the shots. Atlantis Resort Philippines

I too would like to know what lighting you used. from the image file f5.9 at a 60th ISO 80. Please share you shooting technique. Were you using a diopter of any sorts?

Leaving for East End Grand Cayman on Saturday.. Got the FIX S100 housing and the L&M Solar 500 plus 2 S&S YS-01.

Thanks, guys.
For lighting I use one Ikelite DS161 with EV controller on manual.
I used a diopter in all 3 shots, that is the epoque macro DML-2 which is a +7 diopter.
I usually don't use to much Photoshop on my pictures, just exposure correction and size fitting for the internet.
